Wherein, the outer circumference of the pressing cap 33 is further provided with a sliding cavity 46, the upper side of the sliding cavity 46 is provided with a guiding inclined plane 47, the driving rod 39 is movably arranged in the sliding cavity 46, the upper end of the driving rod 39 is provided with a first matching inclined plane 48 abutting against the guiding inclined plane 47, the lower end of the driving rod 39 is provided with a second matching inclined plane 49 cooperating with the guiding inclined plane 38, one side of the driving rod 39 facing the moving direction of the pressing sleeve 32 is provided with a third elastic element 50, one end of the third elastic element 50 abuts against the driving rod 39, the other end abuts against the side surface of the sliding cavity 46, see fig. 11, the initial position of the driving rod 39 is located above the top end of the guiding inclined plane 38. Here, the elastic force of the elastic member three 50 is smaller than the frictional force when the pressing sleeve 32 rotates.

In order to stabilize the motion state of the driving rod 39 in the sliding cavity 46 and facilitate the installation of the driving rod 39, a cover plate 51 is arranged on the sliding cavity 46 and used for buckling the driving rod 39, a strip-shaped protrusion 52 is arranged on the outer surface of the driving rod 39, a limit groove 53 used for supporting the strip-shaped protrusion 52 is arranged on the inner side surface of the cover plate 51, and the strip-shaped protrusion 52 is arranged in parallel with the guide inclined surface 47.

In this embodiment, the first elastic member 36, the second elastic member 37 and the third elastic member 50 are all springs, and the springs are compression springs.

The movement of the locking device 30 is explained in detail below:

reference is made to fig. 11 and 15 in conjunction with the orientation and condition of fig. 11 and 15.

In the initial state, under the action of the first elastic element 36, the pressing sleeve 32 is separated from the upper surface of the warning hole 24; under the action of the second elastic element 37, the driving rod 39 is separated from the guide inclined plane 38; the drive rod 39 is biased to the left, i.e. away from the resilient member, by the resilient member three 50.

When it is desired to lock the sealing plate 4:

the pressing cap 33 is pressed downwards, and the first elastic piece 36 is slowly compressed because the elastic force of the second elastic piece 37 is far greater than that of the first elastic piece 36; when the bottom surface of the pressing sleeve 32 abuts against the surface of the warning hole 24, the second elastic element 37 is compressed, the driving rod 39 contacts the guiding inclined surface 38 at the moment, and the pressing cap 33 cannot rotate circumferentially, so that the pressing sleeve 32 rotates anticlockwise by 90 degrees in a reverse direction under the action of the guiding inclined surface 38, the second limiting clamping block 35 rotates to the position below the first limiting clamping block 34, and the first limiting clamping block 34 limits the pressing sleeve 32 to ascend.

In the process of pressing down the pressing cap 33, due to the guiding effect of the guiding inclined surface 47 and the resisting effect of the side wall of the pressing sleeve 32, when the pressing cap 33 is pressed down to the end position, the driving rod 39 will overcome the acting force of the elastic element three 50 and move to the right side of the sliding cavity 46. Here, although the third elastic member 50 applies a force to push the guide bar to the left, the force is not enough to push the pressing sleeve 32 to rotate reversely because the force is smaller than the friction force applied to the pressing sleeve 32 in the circumferential direction.

When the pressing cap 33 is released, the pressing cap 33 is rapidly reset under the action of the second elastic element 37, and after the driving rod 39 is separated from the guide inclined plane 38, the driving rod 39 moves towards the left side of the sliding cavity 46 under the action of the third elastic element 50 and returns to the initial position, so that the bottom end of the driving rod 39 is slightly biased above the next guide inclined plane 38 to prepare for the next pressing.

When the locking of the sealing plate 4 needs to be released:

the pressing cap 33 is pressed down again, the driving rod 39 pushes the pressing sleeve 32 to rotate 90 degrees counterclockwise again, and the second limiting clamping block 35 is separated from the first limiting clamping block 34; when the pressing cap 33 is released, the pressing sleeve 32 rises and resets under the action of the first elastic piece 36, so that the pressure on the warning rod 23 is relieved, and the sealing plate 4 can be opened and closed freely.

In the above process, the pressing sleeve 32 rotates counterclockwise by 90 ° every time the pressing cap 33 is pressed, and the locked state and the released state of the sealing plate 4 are cyclically switched.

The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
